The California drought and climate disruption

ClimateProgress covered the jet stream connection on Monday: It will be unseasonably chilly in the eastern part of the United States this week, due to a peculiar weather pattern that’s causing deep waves in the jet stream. One of those big waves is bringing cool air down from the northeast Pacific and the Arctic. This…

Time history of atmospheric carbon dioxide (2013 data)

Video credit: Andy Jacobson, CIRES/NOAA In 2013, Greenhouse gases continued to rise, 34 percent increase since 1990 NOAA reported in May 2014, about greenhouse gas observations, based on the Annual Greenhouse Gas Index (AGGI). Findings show that greenhouse gasses keep rising, a trend observed since the Industrial Revolution (1880s) and has accelerated in recent decades. The main contributor…

Antarktischer Eisschild hat in der Vergangenheit zum rasanten Meeresspiegelanstieg geführt

Alfred-Wegener-Institut, 28 Mai 2014: Der Antarktische Eisschild hat zum Ende der letzten Eiszeit in kurzer Zeit sehr viel Eis verloren und damit den Meeresspiegel weltweit rasant um mehrere Meter ansteigen lassen.  Mit ihrer Studie liefern die Wissenschaftler den ersten Beweis dafür, dass der Massenverlust des Antarktischen Eisschildes wesentlich dazu beigetragen hat, dass der Meeresspiegel am Ende…

Why is Antarctic sea ice expanding?

By Laura Naranjo (NSIDC), first published January 31, 2014. In the following  an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…

New mechanism uncovered, causing potentially rapid Antarctic Glacier melt

An Australian-led research team found that sea levels may rise much faster than previously predicted by models, because changes by disruptive westerly winds, weren’t taken into account. Conservative estimates so far, projected irreversible melting in the course of a few centuries, depending on the temperature increase. Related Each degree of global warming might ultimately raise…

The Runaway Glaciers in West Antarctica

NASA/JPL press release, May 12, 2014: A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea. The study presents…

Canada’s shocking oilsands operation (Aerial footage)

DeSmog Canada published a series of aerial photos from Canada Alberta. Alex MacLean is one of America’s most famed and iconic aerial photographers. His perspective on human structures, from bodies sunbathing at the beach to complex, overlapping highway systems, always seems to hint at a larger symbolic meaning hidden in the mundane. By photographing from above, MacLean shows…

With further Arctic Amplification, How fast will Greenhouse Gas emissions accelerate in the Arctic Circle?

Introduction to Methane Hydrate “Methane Hydrates and Contemporary Climate Change” (2011) IDENTIFICATION This post “A Mechanism for Shallow Methane Hydrate Dissociation”, explores possible mechanism which could release vast quantities of shallow Methane Hydrate into the ocean and atmosphere.       CH4 Release The following studies explore the release of CH4 emissions in the Arctic region. OBSERVATION…
